对于这个链接 http://bits.blogs.nytimes.com/2014/09/02/uber-banned-across-germany-by-frankfurt-court/?partner=rss&emc=rss 这段代码不起作用,但是如果我为example放另一个:https://www.google.com 一切都很好:
URL url = new URL("http://bits.blogs.nytimes.com/2014/09/02/uber-banned-across-germany-by-frankfurt-court/?partner=rss&emc=rss");
URLConnection uc;
uc = url.openConnection();
uc.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_7; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.205 Safari/534.16");
uc.addRequestProperty("referer", "http://www.facebook.com");
uc.connect();
this.input = uc.getInputStream();
我得到这个例外:
java.lang.IllegalArgumentException: protocol = http host = null

我的代码有什么问题?
